Wherein fig. 2 to 4 only cut the lower end portion of the swivel arm and the wind shielding member, and the other structures are not cut. The cross-section of fig. 2 and 3 avoids the auxiliary blowers and the cross-section of fig. 4 penetrates the auxiliary blowers. Fig. 3 and 5 illustrate the stop 1023 and stop 25 in dashed lines to show that they are blocked from view by the arm 20.
As shown in fig. 1 to 5, the wall-mounted air conditioner indoor unit according to the embodiment of the present utility model may generally include a housing 10, two swivel arms 20, and a wind shielding member 30.
The casing 10 is provided with an air outlet 12 for blowing out an air-out airflow to adjust the indoor environment. When the air conditioner is used for refrigerating/heating, the air outlet air flow is cold air/hot air. The air outlet 12 may be a strip with a length direction parallel to a transverse direction (transverse direction is shown in fig. 1) of the housing 10.
Specifically, the wall-mounted air conditioner indoor unit can perform cooling/heating by using a vapor compression refrigeration cycle system. An indoor heat exchanger and a fan (not shown) are provided in the casing 10. The indoor side heat exchanger and the throttling device are connected with a compressor, an outdoor side heat exchanger and other refrigerating elements arranged in the air conditioner outdoor unit through pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan, indoor air enters the interior of the shell 10 through the air inlet 11 of the shell 10, and after forced convection heat exchange with the indoor side heat exchanger is completed, heat exchange air is formed and enters the air duct, and then is blown to the indoor environment through the air outlet 12. An air deflector 50 is provided at the air outlet 12 for guiding the direction of the air. In addition, the air deflector 50 also has a function of closing the air outlet 12.
The upper ends of the two swivel arms 20 are respectively rotatably mounted on the outer sides of the lateral end caps 102 of the housing 10 about the same lateral axis. The lateral direction herein refers to the lateral direction of the housing 10, with a lateral axis x1, with reference to fig. 1.
Both lengthwise ends of the wind shielding member 30 are respectively connected to lower ends of the two swivel arms 20 so as to swivel with the swivel arms 20. The lengthwise direction of the wind shielding member 30 is parallel to the widthwise direction of the case 10. The wind shield 30 has a wind shielding position facing the air outlet 12 to guide the flow of the air outlet thereof, as shown in fig. 1 to 3. In addition, at least one auxiliary fan 60 is installed on the wind shielding member 30 for blowing the air-out flow flowing thereto toward the indoor environment when the wind shielding member 30 is in the wind shielding position.
In the wall-mounted air conditioner indoor unit provided by the embodiment of the utility model, the wind shielding piece 30 can rotate to the wind shielding position, so that the air flow of the air outlet is shielded, and the discomfort of a human body caused by direct blowing of cold air/hot air in a short distance is avoided. Further, since the wind shielding member 30 is connected to the housing 10 through the swivel arm 20, the radius of rotation is larger and the displacement range is larger. In addition, since the auxiliary fan 60 is installed on the wind shielding member 30, when the wind shielding member 30 is at the wind shielding position, the auxiliary fan 60 can be started to blow the air outlet airflow flowing to the wind shielding member to the indoor environment, so that the diffusion of the air outlet airflow is quickened, and the air outlet quantity of the air outlet 12 is prevented from being blocked due to the additional installation of the wind shielding member 30.
The number of auxiliary blowers 60 may be one, preferably a plurality. For example, as shown in fig. 1, a plurality of auxiliary blowers 60 may be arranged in the longitudinal direction of the wind shielding member 30. Each auxiliary fan 60 is preferably an axial flow fan. The axial flow fan axially intakes air and axially outputs air, the air path is not turned, and the axial flow fan is particularly suitable for conveying air flow on one side of the wind shielding piece 30 to the other side of the wind shielding piece 30.
In some embodiments, as shown in fig. 4, the housing 10 is further provided with an air inlet 11. The wind shielding member 30 is configured to be rotatable with the two rotating arms 20 to an auxiliary air intake position facing the air intake 11, so that indoor air is blown toward the air intake 11 by rotating the auxiliary fan 60 in a reverse direction (when the wind shielding member 30 is in the wind shielding position, the direction of rotation of the auxiliary fan 60 is defined as a forward direction), thereby forming an air intake boosting effect, increasing the air intake amount, and improving the air conditioning efficiency.
In some embodiments, as shown in fig. 5, the wind shield 30 may be configured to rotate with the two swivel arms 20 to a conventional position below the bottom wall 103 of the housing 10 so as not to interfere with the conventional air outlet of the air outlet 12.
FIG. 6 is a schematic illustration of the engagement of the swivel arm 20 with the exploded construction of the windshield 30 of FIG. 1;
in some embodiments, as shown in fig. 6, the wind shield 30 is a double layer grille structure to allow airflow to penetrate. The wind shield 30 includes an inner grill layer 31 and an outer grill layer 32 that are fixed to each other. It will be appreciated that both the inner and outer grill layers 31, 32 have grill holes to allow airflow to penetrate. When the wind shield 30 is in the wind shielding position, the inner grill layer 31 faces the air outlet 12, constituting the "inner side" of the wind shield 30. The outer grill layer 32 is oriented toward the outdoor environment, constituting the "outside" of the wind shield 30. Each auxiliary blower 60 is disposed between the inner grill layer 31 and the outer grill layer 32. This arrangement facilitates the installation of the auxiliary blower 60 and also allows the auxiliary blower 60 to be wrapped to avoid adverse effects on the appearance of the wind shield 30.
Further, as shown in FIG. 6, the outer grill layer 32 includes a plurality of parallel air guide grills 322. Specifically, each air guide grate bar 322 is parallel to the length direction of the wind shield 30. The wind guide bars 322 are arranged at intervals along the width direction of the wind shielding member 30, and the interval space between every two adjacent wind guide bars 322 is used for air outlet.
The wind shielding member 30 can be mounted to the two swivel arms 20 in two postures. The second posture is changed in installation position of both ends of the wind shielding member 30 in the longitudinal direction as compared with the first posture. For example, in the first posture, the C1 end of the wind shielding member 30 in the longitudinal direction is attached to the left-side swivel arm 20, and the C2 end is attached to the right-side swivel arm 20, as shown in fig. 6. In the second posture, the C1 end is mounted to the right swivel arm 20 and the C2 end is mounted to the left swivel arm 20.
In this way, the wind shielding member 30 is mounted on the two rotating arms 20 in the first posture, and when the wind shielding member is in the wind shielding position, the wind-out airflow is guided forward or upward by the plurality of wind guiding grilles 322, as shown in fig. 3. Those skilled in the art of air conditioning will recognize that upward direction herein means directing the flow of air-out forward upward or directly upward so as to "rise. In the refrigerating mode, the density of the cold air is high, so that the cold air can be blown forward or upward, and the refrigerating speed can be increased. When the wind shielding member 30 is mounted to the two rotating arms 20 in the second posture and is positioned at the wind shielding position, the plurality of wind guiding grilles 322 guide the flow of the exhaust air to sink. It is known to those skilled in the art of air conditioning that sinking guiding herein refers to guiding the flow of the exhaust air forward downward, downward or rearward downward so that it better reaches the ground. Under the heating mode, the density of hot air is smaller, so that hot air sinks and blows out, the heating speed can be increased, and the heating effect near the ground is improved.
FIG. 7 is an enlarged view at A of FIG. 6; fig. 8 is another perspective view of the wind shield 30 of fig. 7.
As shown in fig. 7 and 8, the lower end of each swivel arm 20 has a receptacle 262. The slider 35 is attached to both ends of the wind shielding member 30 in the longitudinal direction. The slider 35 is translatably mounted to the wind shield 30, and the slider 35 has a mounting shaft 352 (refer to fig. 8). The mounting shaft 352 is adapted to be inserted into the receptacle 262 to secure the windshield 30 to the swivel arm 20. Specifically, during assembly, the arm 20 is first aligned with the bottom of the windshield 30, and then the slider 35 is slid (in the x-axis forward direction) so that the mounting shaft 352 is inserted into the receptacle 262. Specifically, as shown in fig. 8, the sliding block 35 is provided with a sliding groove 355, and the wind shielding member 30 is provided with a sliding rail 302, and the sliding rail 302 is inserted into the sliding groove 355 to guide the sliding block 35 to slide. The wind shielding piece 30 is provided with two rows of L-shaped buckles 301, and the sliding block 35 is positioned between the two rows of L-shaped buckles 301, so that the sliding block 35 is buckled by the two rows of L-shaped buckles 301, and the normal direction of the sliding block is prevented from being separated from the wind shielding piece 30, so that the sliding block can only slide in a translation way.
Further, as shown in fig. 7 and 8, the bottom end of each rotating arm 20 is bent out of a mounting plate 26 in the transverse direction, so that the rotating arm 20 is in an "L" shape as a whole, and a jack 262 is formed in the mounting plate 26. Specifically, the surface of the mounting plate 26 may have a protrusion, and the protrusion is provided with a receptacle 262. The slider 35 is slidably mounted on a side (z-axis negative side) of the wind shield 30 facing the mounting plate 26, and is provided with a handle portion 351. The handle portion 351 penetrates the relief hole 34 of the wind shield 30 to protrude to a side (z-axis forward side) of the wind shield 30 facing away from the mounting plate 26, so that the user operates the handle portion 351 to push the slider 35 to slide.
Further, as shown in fig. 7 and 8, the mounting plate 26 is also provided with a guide groove 265 connecting the insertion holes 262 for guiding the mounting shaft 352 into the insertion holes 262. During assembly, the mounting shaft 352 may be allowed to more smoothly enter the receptacle 262. The mounting plate 26 is provided with a detent projection 263 (as shown in fig. 7), and a side of the wind shielding member 30 facing the mounting plate 26 is provided with a stop projection 305, and the detent projection 263 is snapped on a side of the stop projection 305 near the lateral center of the wind shielding member 30 to prevent misalignment of the wind shielding member 30 and the swivel arm 20 in the lateral direction.

As shown in fig. 7, a second gear 85 for transmission is provided between the first motor 83 and the first gear 86. The number of teeth of the second gear 85 is smaller than that of the first gear 86 so as to achieve a deceleration effect. The first motor 83 is a stepping motor.
As shown in fig. 10 and 11, each end cap 102 may be provided with a first relief hole 1021, and an outer side surface thereof protrudes outwards to form a mounting ring 1025. Specifically, mounting ring 1025 may be extended outwardly from the edge of first relief hole 1021. Each swivel arm 20 is hood-like opening toward the end cap 102 to cover the end cap 102 to provide a cleaner appearance. The cover-shaped rotating arm 20 has a bottom wall substantially parallel to the end cap 102 and a side wall extending from an edge of the bottom wall to be bent toward the end cap 102. The upper end of each swivel arm 20 has a circular first sleeve portion 201, the first sleeve portion 201 rotatably fitting around the outer periphery of the mounting ring 1025 to provide rotatable connection of the swivel arm 20 to the end cap 102. The transmission part 21 inside the first sleeve part 201 passes through the first relief hole 1021 to be connected to the driving device 80 inside the end cover 102. The first abdication hole 1021 plays an abdication role.
The end surface of the first gear 86 protrudes to form a driving ring 861 coaxial with the first gear, and the driving ring 861 has a plurality of positioning notches 8610 arranged circumferentially. Each of the driving parts 21 has a plurality of positioning tabs 216, and each of the positioning tabs 216 is inserted into one of the positioning notches 8610 so that the first gear 86 transmits power to the rotating arm 20. For example, in fig. 10, each of the driving parts 21 has four positioning pieces 216, and is arranged in a cross shape. Accordingly, the number of positioning notches 8610 is four.
In some embodiments, as shown in fig. 10 and 11, each driving device 80 further includes a case body 81 and a case cover 82, which are fastened together to form a driving case. The case 81 is disposed inside the end cover, and the first motor 83 is mounted on the outer side surface of the case 81, that is, between the case 81 and the end cover 102. Specifically, the first motor 83 is connected to the screw hole 813 of the case 81 by a screw 833.
The box cover 82 is covered and buckled on the box body 81, the first gear 86 is located between the box body 81 and the box cover 82 and is rotatably installed on the box cover 82, and the transmission ring 861 extends to the outer side of the box body 81 through the second yielding hole 811 of the box body 81. A second gear 85 is also mounted to the cover 82. The cover 82 is provided with mounting holes 821, 823 to mount the first gear 86 and the second gear 85, respectively. The rotary shaft 832 of the first motor 83 passes through the hole 812 formed in the case 81 so as to protrude into the inside of the case 81 to be connected to the second gear 85.
The cover 82 is preferably screwed to the end cap 102 so that the case 81 can be clamped between the cover 82 and the end cap 102 by fixing only the cover 82, which corresponds to fixing the case 81 at the same time.
In some embodiments, as shown in fig. 3 and 5, a limiting portion 1023 is disposed on the outer side of at least one end cap 102, so as to block the rotating arm 20 from continuing to rotate backward when the corresponding rotating arm 20 drives the wind shield 30 to rotate backward to the normal position (as shown in fig. 5), so that the wind shield 30 accurately stays at the normal position. The outer sides of both end caps 102 are preferably provided with a stopper 1023.
Each of the stopper portions 1023 is formed in a convex shape protruding from the outer side surface of the end cap 102, and the corresponding swivel arm 20 has a stopper portion 25 extending toward the end cap 102.
